M2 not detected on Khadas board

Description

Hey,

I want to connect the dual edge tpu accelerator to my Khadas VIM 3 board. After a fresh install of Ubuntu 20.04 with the mainline kernel (5.16) I am unable to detect the borad.

Both lspci -nn | grep 089a and ls /dev/apex_0 return nothing.

Output modinfo gasket:

Any ideas where to look for the problem?

Thanks
